Fatented Sept. 30, 19 52 SANDING AND ABRAD NGPAn HoraceE. Longley, Elmira, Ni YL, assignor of onethird to Arthur A. Linster, Elmira, N. Y. Application May 8, 1950', Serial Ne. 160,800 Claims. (Cl. 551-136) This invention relates to new and useful improvements in sanding and abrading' pads and the primary object of thepresent invention is to provide a pad that will conform to any irregular surface upon which it is being used and more particularly a pad for use with the sanding and abrading head disclosed in my patent numbered 2,475,972.

Another important object of the present invention is to provide a sanding and abradlng pad molded of a flexible plastic material or pressed from paper into the proper form, and an abrasive secured to the outer surface of whichever type material is used.

Yet another object of the present invention is to provide a sanding and abrading pad of varying sized grit, from coarse rapid cutting to fine polishing and bufiing grade, so that an operator may quickly clean and smooth a surface and then bring the same surface to a high polish.

A further object of the present invention is to provide a sanding and abrading pad for use with a rotary head having a series of circumferentially spaced teeth wherein the pad is integrally formed with teeth that will be interdigitated with the teeth on the head to provide a positive driving connection between the pad and the head, thereby eliminating any possible loss of efilciency through slippage of the pad upon the head and to permit heavier cuts to be taken and the work accomplished more quickly and with a more uniformly finished surface.

A still further aim of the present invention is to provide a sanding and abrading pad that is simple and practical in construction, strong and reliable in use, inexpensive to manufacture, and otherwise Well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a plan View of the present sanding and abradingpad;

Figure 2 is a sectional View taken substantially on the plane of section line 2-2 of Figure 1 and showing a rotary head in section within the pad and having teeth interlocked with the teeth of the pad; and,

Figure 3 is a fragmentary perspective view of the present pad'to illustrate the locking teeth forming part thereof.

Referring now to the drawings in detail,.

wherein for the purpose of illustration, thereis disclosed a preferred embodiment of the present I invention, thenumeral Iii represents a bulbousor sac-like body molded ofa flexible plastic material, such as rubber, or'pres'sed from paper. into the desired shape. The body is of circular form at its diameter and of elliptical form when sectioned in a vertical median plane as shown in Figure 2.

The body I0 is provided with a circular opening and the edge defining the opening is integrally formed with a circular flange l2 having a plurality of circumferentially spaced radially disposed teeth l4 that extend into the opening in thebody.

The outer surface of the body I!) is coated with an abrasive material. The abrasive surface will be of any sized grit, from coarse rapid cutting to fine polishing and bufiing grade, depending upon the article being worked or the degree of polish desired.

In practical use of the present invention, a rotary head H is inserted into the body Ill and the head is provided with a series of circumfer entially. spaced radial teeth Ma that will be interdigitated with the teeth [4 to establish a positive .1001: between the head and the pad so that the pad or body It will rotate effectively with the head, and thereby eliminates any possible loss of efficiency through slippage of the pad l0 upon the head.

As the gear-tooth driving ring l2, I l is molded integrally with the rest of the pad body It, it will not tear or break loose from the body when the pad is in use. r

In View of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art.

A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appendedclaims.

Having thus described the invention, what'is claimed as new is: a

1. A sanding and abrading pad comprising, a

' hollow, soft pliable body havingan abrasive surface, said body being open at one end to receive a rotary head, and a plurality of circumferentially spaced radially disposed imperforate teeth at the open end of said body and constituting 3 the sole means for holding the body against rotation relative to a rotary head inserted in the body, said teeth being considerably thicker than the walls of said body.

2. In combination with a rotary head having a series of circumferentially spaced teeth thereon, a sanding and abrading pad comprising a saclike body receiving the rotary head and having a roup of circuinferentially spaced teeth interdigitated with the teeth of said head.

3. A surface treating pad comprising a hollow, soft pliable one piece body of resilient material adapted to yieldingly embrace a rotary head, said body having an opening therein, a continuous flange about the opening, and a plurality bf circumferentially spaced radially disposed 1111138110.- rate teeth integrally formed riphery of said flange and forming the sole means for preventing rotation of the body relative to a rotary head inserted therein, said teeth and said flange being considerably thicker than the walls of said body. i g 4 4.
